how brilliant that you/daughter had a right result with both physio and orthobod!
re sleeping- (sorry mods for going ot-but I could only find a very very old and rather short thread on sleep - which quite surprised me as there's bucket loads of posts on sleep)-
in puberty in general the circadian rhythm (which kinda governs our 24hr sleep/wake cycles) does go haywire- giving an effect similar to being jet lagged- if you google 'circadian rhythm puberty' there's loads of reputable info to be found on this- so maybe she is just a 'normal teenager'
in that respect
my feeling is though ... that maybe in bendy teenagers this normal circadian rhythm 'haywireness' might be more 'extreme'...
"good sleep hygienie" might help a wee bit (again google this- but beware mostly they also say 'no reading in bed'
- but if I dont read in bed I cant get to sleep cause my brain just wont shut up
)- and again my feeling is that we bendies may need longer 'winding down' time
IF (it wont necessarily happen!!) your daughter begins to have problems with getting dizzy/fainty whilst standing, when getting up from sitting for a while and/or starts to feel unrefreshed from sleep even if she has slept as long as she wanted to (like on week ends)... then maybe there is something up with her autonomic nervous system... this is rather common in us bendies (though it seems teenagers in general are a bit prone to this, but normal teens seem to totally grow out of it, bendies seem to tend to keep having phases of it/or at worst permanent problems with it)
is a great talk by an EDS/HMS/autonomic dysfunction/sleep disorder savvy doc- it also talks about bendies indeed having a 'hyperreacting' adrenaline/cortisol thing going on which makes it harder to 'switch off'/'settle'
and for good general information on autonomic dysfunction you could have a look at stars.org.uk
oh and... MADMUM too (sorry I am kinda shouting
but just to make you notice this amongst my long blabla- as this might be helpful for your son too) - if it's more general discomfort/achiness (rather than bad pain/ pain somewhere in particular) that gets in the way of getting to sleep-
then progressive/active muscle relaxation exercises done before/ in bed might help too-
our muscles have to work harder than normals=get tense easier, but we also have a tendency to unnecessarily tense muscles too much whilst doing things, this is usually most obvious in things that involve gripping- so sometimes our muscles just dont relax by themselves which is uncomfortable, can make you feel achy, can even be downright painful.
